Namada Interface Indexer

A set of microservices that crawler data from a namada node, store them in a postgres database and serve them via a REST api.

🔧 This is currently being worked on. Don't expect things to work! 🔧

Architecture

The indexer is composed of a set microservices and a webserver, each one of these lives in his own crate. Each microservice is responsible of indexing some data from the chain and store them in the postgres database. Right now, there are 4 microservices:

• chain: goes block by block and fetches information from transactions (e.g balances)
• pos: fetches the validator set each new epoch
• rewards: fetches PoS rewards each new epoch
• governance: fetches new proposal and the corresponding votes

The webserver is responsible to serve the data via a REST API, which are described in the swagger.yml file in the project root.

How to run

• Get a Namada RPC url
  • Either create a local chain
  • Or use a Public RPC
• Change CHAIN_ID and CHECKSUMS_FILE env variable and file
• Install just
• Run just docker-run

Testing via seeder

Instead of fetching data from a running network, for testing porpuses it's also possible to populate the databse with some random data.

• cargo build
• cd seeder && cargo run -- --database-url postgres://postgres:password@0.0.0.0:5435/namada-indexer

It's possible to only run the webserver and have access to the data via API.
